Hi. Should the clutch be bled at the same time the brakes are flushed? I read the clutch hydraulics piggyback off the brake lines. If the clutch line contains old brake fluid won’t it mix in with the new brake fluid and defeat the purpose of clean brake lines? Thanks for input.

FYI - the shwaben pressure bleeder is a great tool for a DYI. one note-the reservoir filter needs to be removed to pressurize.

 

Did do that with my 964...changed the line too.

 

Most owners change the fluid in both systems at the same time.

Seems logical. Thanks!

 

Makes sense to me. Thanks!

 

Opening up this older thread as I would like to get the opinion of some of you more experienced with Porsche maintenance. I recently flushed my brakes and slave cylinder. After flushing the clutch with the pedal in the normal position I read the forums and the service manual and noticed I should depress the clutch to the floor before bleeding. I knew I was not supposed to let it fall to the floor however I thought I still had pressure so I just pushed it down and it slammed to the floor... Of course! I then finished the bleed and everything seems fine. My question is what is the likelihood I damaged a seal by letting the clutch fall to the floor this one time? I now have pressure and everything feels fine. I however had read somewhere that the fear is that the seal could be damaged from this and cause a failure down the road. Curious is this is something I should be concerned with or if it is likely OK. Thank you in advance for any input anyone may have!

If you haven't noticed problems with the pedal feel, I'm guessing low mileage car? I've actually never seen someone mess up the clutch cylinder this way. I have known people to mess up a brake cylinder this way and they usually realize what they did within a couple of days of driving (when it does damage the seal, it seems to significantly damage it)

 

Thank you for the reply marlinspike. The car has 29k miles so yeah it is a low miler. I have it put away for the winter so I haven't had it out on the roads yet for a real test. Here in New Hampshire the roads are terrible from December to April... In the garage however I have good pedal feel and it "seems" ok. I appreciate you taking the time to reply, I will hope for the best!
